The turbulence of contemporary migrations and postcolonial processes brings to the continuous redefinition of geographical spaces and borders, which cannot simply be considered lines of distinction and separation, but fluid and changing contours, rewritten and reshaped by those who go along and beyond them. Drawing maps and rewriting boundaries sometimes become a symbolic process of redefinition of one's own identity, as in the novel "La mia casa è dove sono", in which the italo-somali writer Igiaba Scego builds a new geographical map, where the town of Rome, transfigured by History and Geography, assumes a new physiognomy and becomes, also, Mogadishu.
